WebIn Magnetic Resonance Imaging (MRI), the K-space data is often under-sampled and truncated to shorten the scan time. However, the truncation of K-space also causes … WebAs a first step solution, ArtifactID identifies wrap-around and Gibbs ringing in low-field brain MRI. We utilized two datasets: 179 T 1 -weighted pathological brain images from a 0.36 T scanner and 581 publicly available T 1 -weighted brain images.
WebAnother particular feature of our deep learning model is its ability to suppress artifacts.
